RICHARD W. HUBBARD, OF ASHTABULA, OHIO.

WIN DOW-STOP.

Application filed January 20, 1908.

To all whom it may concern:

Be it known that I, RIoIiAnn IV. Hua nano, citizen ot the United States, residing at Ashtabula, iu the county of Ashtabula and State of Ohio, have invented new and useful Improvements in Window-Stops, of which the following is a specification.

My invention pertains to stops for sliding window sashes, doors and the like; and it consists in the peculiar and advantageous Stop hereinafter described and particularly pointed out in the claim appended.

The novel stop is designed more particularly for use in combination with the sliding sashes of a window; the metallic sheath being socketed in one side bar of the upper sash with its exposed end flush with the face of said side bar, and the spring-key being adapted, when arranged in the socket, to eX- tend therefrom and lie in the path of the meeting rail of the lower sash; this relative arrangement of parts being advantageous since either sash can be opened to a limited extent, say four inches, or an opening of corresponding size may be provided at either the lower end or the upper end of the window for ventilating purposes without danger of an unauthorized person being able to move either sash past the stopping point; also, since when the spring-key is removed from the sheath, the sashes may be freely moved in the ordinaaiy manner relative to each other. The said relative arrangement of parts is further advantageous since when o my improvements are employed in addition to a sash lock, the spring-key will baffle the attembt of an unauthorized person to enter the window even if such person succeds in prying off the sash lock.

In the accompanying drawings forming part of this specification: Figure l is a view illustrating my novel stop as applied to the upper sash of a window. F ig. 2 is an enlarged vertical section taken through the meeting portions of the sashes and also through my novel stop and showing the spring-key in side elevation, and: Fig. 3 is a perspective view of the spring-key reA moved.

Similar letters designate corresponding parts in all of the views of the drawings, referrino` to which:

A is the lower sash, and B, the upper sash of a Window, While O is the sheath of my novel stop and D the spring-key thereof.

The sheath C is socl eted in one side bar Specification of Letters Patent.

of the upper sash B; the said sheath being open at both ends and the inner end ot its wall being beveled or sharpened, as indicated by o, to facilitate its introduction. It will also be noticed that the exposed end of the sheath is flush with the face of the side bar to prevent the sheath from interfering with free movement of the sashes when the spring-key is removed, and that a chamber b is provided at the inner end of the sheath and in the sash for a purpose presently set forth.

The spring-key D is formed of a single piece of metal bent upon itself to form an eye c and stem portions d, and the ends of the said stem portions d are beveled, as indicated by c to facilitate the ready insertion of the stem of the key in the sheath C. At this point attention is directed to the fact that when the stem of the spring-key is arranged in the sheath C as best shown in Fig. 2, the portions of the said stem tend to spring outward and by so doing exert considerable pressure against the wall of the sheath, with the result that there is no liability of the spring-key being displaced by shaking of the sashes or otherwise. It will also be observed that the ends of the stem portions serve by extending into the chamber L and engaging the inner sharp end of the sheath to assist in preventing casual displacement of the spring-key. Notwithstanding the fact that there is no liability of the spring-key being casually displaced from its sheath, it will be readily understood that when desired the said spring-key may be ex peditiously and easily Withdrawn from the sheath to permit of the before mentioned free movements of the sashes relative to each other.

In the position shown in Figs. 1 and 2, it will be appreciated that my novel stop is possessed of all of the practical advantages hereinbefore ascribed to it; and it will also be appreciated that the stop, particularly when the saine is nickel plated or otherwise embellished, is calculated to enhance rather than detract from the finished appearance of a window. It will further be noted that the stop as a whole is strong and durable and therefore wel]` calculated to resist powerful efforts to move the sashes beyond the stopping point.

Having described my invention, what I claim and desire to secure by Letters-Patent, 1s:

The combination in a Window stop, of lower and upper slidin sashes; the upper sash being provided in t e face of one of its side bars with a socket, a metallic sheath open at its ends and having the outer side of its Wall beveled at its inner end to render the said end sharp; the said sheath being arranged in the socket with its outer end Hush with the face of the sash bar and being of a less length than the socket, whereby :L chamber is formed between its inner end and the inner end of the socket, and a spring-key removably arranged in the sheath; the said spring-key being formed of a single piece of metal Which is bent upon itself to provide an eye, and opposed Stem portions extending from the eye, and the said stern portions being longer than the Sheath and beingr bev eled at their ends.

In testimony whereof I have hereunto Set my hand in presence of two subscribing Witmesses.
